Sync Outlook to Google Calendar (Work-Safe, Read-Only)
If your job uses Outlook/Office 365 but your personal life lives in Google Calendar, Outlook's built-in "Publish a calendar" feature gives you an ICS link Google can subscribe to. But Microsoft's own docs note that Google can take 24+ hours to refresh, which makes it useless for last-minute schedule changes. CalPilot mirrors the same ICS link with 15-minute refresh.
Why sync Outlook to Google Calendar?
Most people's work and personal calendars live on different platforms — Outlook for the job, Google for the family. Outlook lets you publish a read-only ICS link to share that calendar, but anything that subscribes to it via Google's native flow refreshes slowly. CalPilot polls the same Outlook-published link every 15 minutes and writes events into your personal Google Calendar without ever needing your work credentials.

Common issues and fixes
My company has disabled calendar publishing
Common for corporate Office 365 tenants. Workarounds: ask IT to enable it, or use Microsoft Graph OAuth (CalPilot Premium feature, if you build it). There's no other reliable way.Private events show "Private Appointment"
Outlook strips details from private-marked events when publishing — that's intentional Microsoft behavior, not a bug.Recurring meetings duplicate
Some recurring rules don't translate cleanly between Outlook's exceptions handling and Google's iCal parser. CalPilot normalizes these.Events show in the wrong time zone
Confirm your Outlook account timezone matches your Google Calendar default. Mismatches cause time drift.
